Mies was a director of the Bauhaus, a seminal school in modern architecture.[2] After Nazism's rise to power, and with its strong opposition to modernism (leading to the closing of the Bauhaus itself), Mies went to the United States. He accepted the position to head the architectural school at the Illinois Institute of Technology, in Chicago.

Mies sought to establish a new architectural style that could represent modern times just as Classical and Gothic did for their own eras. He created a new twentieth-century architectural style, stated with extreme clarity and simplicity. His mature buildings made use of modern materials such as industrial steel and plate glass to define interior spaces. He strove toward an architecture with a minimal framework of structural order balanced against the implied freedom of unobstructed free-flowing open space. He called his buildings "skin and bones" architecture. He sought an objective approach that would guide the creative process of architectural design, but was always concerned with expressing the spirit of the modern era. He is often associated with his fondness for the aphorisms, "less is more" and "God is in the details".

Ludwig Mies renamed himself as part of his transformation from a tradesman's son to an architect working with Berlin's cultural elite, adding "van der" and his mother's maiden name "Rohe" (the word mies means "lousy" in German[7])[8][9] and using the Dutch "van der", because the German form "von" was a nobiliary particle legally restricted to those of genuine aristocratic lineage.[10] He began his independent professional career designing upper-class homes.[citation needed]

In 1913, Mies married Adele Auguste (Ada) Bruhn (1885-1951), the daughter of a wealthy industrialist.[11] The couple separated in 1918, after having three daughters: Dorothea (1914-2008), an actress and dancer who was known as Georgia, Marianne (1915-2003), and Waltraut (1917-1959),[12] who was a research scholar and curator at the Art Institute of Chicago. During his military service in 1917, Mies fathered a son out of wedlock.[13] In 1925 Mies began a relationship with designer Lilly Reich that ended when he moved to the United States; from 1940 until his death, artist Lora Marx (1900-1989) was his primary companion. Mies carried on a romantic relationship with sculptor and art collector Mary Callery for whom he designed an artist's studio in Huntington, Long Island, New York.[14] He also was rumored to have a brief relationship with Edith Farnsworth, who commissioned his work for the Farnsworth House.[15][16] Marianne's son Dirk Lohan (b. 1938) studied under, and later worked for, Mies.

After World War I, Mies began, while still designing traditional neoclassical homes, a parallel experimental effort. He joined his avant-garde peers in the long-running search for a new style that would be suitable for the modern industrial age. The weak points of traditional styles had been under attack by progressive theorists since the mid-nineteenth century, primarily for the contradictions of hiding modern construction technology with a facade of ornamented traditional styles.

The mounting criticism of the historical styles gained substantial cultural credibility after World War I, a disaster widely seen as a failure of the old world order of imperial leadership of Europe. The aristocratic classical revival styles were particularly reviled by many as the architectural symbol of a now-discredited and outmoded social system. Progressive thinkers called for a completely new architectural design process guided by rational problem-solving and an exterior expression of modern materials and structure rather than, what they considered, the superficial application of classical facades.

While continuing his traditional neoclassical design practice Mies began to develop visionary projects that, though mostly unbuilt, rocketed him to fame as an architect capable of giving form that was in harmony with the spirit of the emerging modern society. Boldly abandoning ornament altogether, Mies made a dramatic modernist debut with his stunning competition proposal for the faceted all-glass Friedrichstraße skyscraper in 1921, followed by a taller curved version in 1922 named the Glass Skyscraper.[17]

He joined the German avant-garde, working with the progressive design magazine G, which started in July 1923. He developed prominence as architectural director of the Werkbund, organizing the influential Weissenhof Estate prototype modernist housing exhibition. He was also one of the founders of the architectural association Der Ring. He joined the avant-garde Bauhaus design school as their director of architecture, adopting and developing their functionalist application of simple geometric forms in the design of useful objects. He served as its last director.

Like many other avant-garde architects of the day, Mies based his architectural mission and principles on his understanding and interpretation of ideas developed by theorists and critics who pondered the declining relevance of the traditional design styles. He selectively adopted theoretical ideas such as the aesthetic credos of RussianConstructivism with their ideology of "efficient" sculptural assembly of modern industrial materials. Mies found appeal in the use of simple rectilinear and planar forms, clean lines, pure use of color, and the extension of space around and beyond interior walls expounded by the DutchDe Stijl group. In particular, the layering of functional sub-spaces within an overall space and the distinct articulation of parts as expressed by Gerrit Rietveld appealed to Mies.[citation needed]

The design theories of Adolf Loos found resonance with Mies, particularly the ideas of replacing elaborate applied artistic ornament with the straightforward display of innate visual qualities of materials and forms. Loos had proposed that art and crafts should be entirely independent of architecture, that the architect should no longer control those cultural elements as the Beaux Arts principles had dictated. Mies also admired his ideas about the nobility that could be found in the anonymity of modern life.[citation needed]

The bold work of leading American architects was admired by European architects.[citation needed] Like other architects who viewed the drawings in Frank Lloyd Wright's Wasmuth Portfolio, Mies was enthralled with the free-flowing spaces of inter-connected rooms that encompass their outdoor surroundings, as demonstrated by the open floor plans of the Wright's American Prairie Style. American engineering structures were also held up as exemplary of the beauty possible in functional construction, and its skyscrapers were greatly admired.[citation needed]

Commission opportunities dwindled with the Great Depression after 1929. Starting in 1930, Mies served as the last director of the faltering Bauhaus, at the request of his colleague and competitor Walter Gropius. In 1932, Nazi political pressure forced the state-supported school to leave its campus in Dessau, and Mies moved it to an abandoned telephone factory in Berlin. By 1933, however, the continued operation of the school was untenable (it was raided by the Gestapo in April), and in July of that year, Mies and the faculty voted to close the Bauhaus. He built very little in these years (one built commission was Philip Johnson's New York apartment); the Nazis rejected his style as not "German" in character.

Frustrated and unhappy, he left his homeland reluctantly in 1937 as he saw his opportunity for any future building commissions vanish, accepting a residential commission in Wyoming and then an offer to head the department of architecture of the newly established Illinois Institute of Technology (IIT) in Chicago. There he introduced a new kind of education and attitude later known as Second Chicago School, which became very influential in the following decades in North America and Europe.

Mies settled in Chicago, Illinois, where he was appointed head of the architecture school at Chicago's Armour Institute of Technology (later renamed Illinois Institute of Technology). One of the benefits of taking this position was that he would be commissioned to design the new buildings and master plan for the campus.[19] All his buildings still stand there, including Alumni Hall, the Chapel, and his masterpiece the S.R. Crown Hall, built as the home of IIT's School of Architecture. Crown Hall is widely regarded as Mies' finest work, the definition of Miesian architecture.

In 1944, he became an American citizen, completing his severance from his native Germany.[20] His thirty years as an American architect reflect a more structural, pure approach toward achieving his goal of a new architecture for the twentieth century. He focused his efforts on enclosing open and adaptable "universal" spaces with clearly arranged structural frameworks, featuring prefabricated steel shapes filled in with large sheets of glass.

His early projects at the IIT campus, and for developer Herbert Greenwald, presented to Americans a style that seemed a natural progression of the almost forgotten nineteenth century Chicago School style. His architecture, with origins in the German Bauhaus and western European International Style, became an accepted mode of building for American cultural and educational institutions, developers, public agencies, and large corporations.

Mies worked from his studio in downtown Chicago for his entire 31-year period in America. His significant projects in the U.S. include in Chicago and the area: the residential towers of 860–880 Lake Shore Dr, the Chicago Federal Center complex, the Farnsworth House, Crown Hall and other structures at IIT; and the Seagram Building in New York. These iconic works became the prototypes for his other projects. He also built homes for wealthy clients.

Chicago Federal Center Plaza, also known as Chicago Federal Plaza, unified three buildings of varying scales: the mid-rise Everett McKinley Dirksen Building, the high-rise John C. Kluczynski Building, and the single-story Post Office building. The complex's plot area extends over two blocks; a one-block site, bounded by Jackson, Clark, Adams, and Dearborn streets, contains the Kluczynski Federal Building and U.S. Post Office Loop Station, while a parcel on an adjacent block to the east contains the Dirksen U.S. Courthouse. The structural framing of the buildings is formed of high-tensile bolted steel and concrete. The exterior curtain walls are defined by projecting steel I-beam mullions covered with flat black graphite paint, characteristic of Mies's designs. The balance of the curtain walls are of bronze-tinted glass panes, framed in shiny aluminum, and separated by steel spandrels, also covered with flat black graphite paint.[21][22] The entire complex is organized on a 28-foot grid pattern subdivided into six 4-foot, 8-inch modules. This pattern extends from the granite-paved plaza into the ground-floor lobbies of the two tower buildings with the grid lines continuing vertically up the buildings and integrating each component of the complex. Associated architects that have played a role in the complex's long history from 1959 to 1974 include Schmidt, Garden & Erickson; C.F. Murphy Associates; and A. Epstein & Sons.[23]

Between 1946 and 1951, Mies van der Rohe designed and built the Farnsworth House, a weekend retreat outside Chicago for an independent professional woman, Dr. Edith Farnsworth. Here, Mies explored the relationship between people, shelter, and nature. The glass pavilion is raised six feet above a floodplain next to the Fox River, surrounded by forest and rural prairies.

The highly crafted pristine white structural frame and all-glass walls define a simple rectilinear interior space, allowing nature and light to envelop the interior space. A wood-panelled fireplace (also housing mechanical equipment, kitchen, and toilets) is positioned within the open space to suggest living, dining and sleeping spaces without using walls. No partitions touch the surrounding all-glass enclosure. Without solid exterior walls, full-height draperies on a perimeter track allow freedom to provide full or partial privacy when and where desired. The house has been described as sublime, a temple hovering between heaven and earth, a poem, a work of art.

The Farnsworth House and its 60-acre (240,000 m2) wooded site was purchased at auction for US$7.5 million by preservation groups in 2004 and is now owned and operated by the National Trust for Historic Preservation as a public museum. The building influenced the creation of hundreds of modernist glass houses, most notably the Glass House by Philip Johnson, located near New York City and also now owned by the National Trust.

The house is an embodiment of Mies' mature vision of modern architecture for the new technological age: a single unencumbered space within a minimal "skin and bones" framework, a clearly understandable arrangement of architectural parts.[24] His ideas are stated with clarity and simplicity, using materials that are configured to express their own individual character.

Mies designed a series of four middle-income high-rise apartment buildings for developer Herbert Greenwald: the 860–880 (which was built between 1949 and 1951) and 900–910 Lake Shore Drive towers on Chicago's Lakefront. These towers, with façades of steel and glass, were radical departures from the typical residential brick apartment buildings of the time. Mies found their unit sizes too small for him, choosing instead to continue living in a spacious traditional luxury apartment a few blocks away. The towers were simple rectangular boxes with a non-hierarchical wall enclosure, raised on stilts above a glass-enclosed lobby.

The lobby is set back from the perimeter columns, which were exposed around the perimeter of the building above, creating a modern arcade not unlike those of the Greek temples. This configuration created a feeling of light, openness, and freedom of movement at the ground level that became the prototype for countless new towers designed both by Mies's office and his followers. Some historians argue that this new approach is an expression of the American spirit and the boundless open space of the frontier, which German culture so admired.

Once Mies had established his basic design concept for the general form and details of his tower buildings, he applied those solutions (with evolving refinements) to his later high-rise building projects. The architecture of his towers appears similar, but each project represents new ideas about the formation of highly sophisticated urban space at ground level. He delighted in the composition of multiple towers arranged in a seemingly casual non-hierarchical relation to each other.

Just as with his interiors, he created free flowing spaces and flat surfaces that represented the idea of an oasis of uncluttered clarity and calm within the chaos of the city. He included nature by leaving openings in the pavement, through which plants seem to grow unfettered by urbanization, just as in the pre-settlement environment.

Although now acclaimed and widely influential as an urban design feature, Mies had to convince Bronfman's bankers that a taller tower with significant "unused" open space at ground level would enhance the presence and prestige of the building. Mies' design included a bronze curtain wall with external H-shaped mullions that were exaggerated in depth beyond what was structurally necessary. Detractors criticized it as having committed Adolf Loos's "crime of ornamentation". Philip Johnson had a role in interior materials selections, and he designed the sumptuous Four Seasons Restaurant, which has endured un-remodeled to today. The Seagram Building is said to be an early example of the innovative "fast-track" construction process, where design documentation and construction are done concurrently.

During 1951–1952, Mies' designed the steel, glass, and brick McCormick House, located in Elmhurst, Illinois (15 miles west of the Chicago Loop), for real-estate developer Robert Hall McCormick, Jr. A one-story adaptation of the exterior curtain wall of his famous 860–880 Lake Shore Drive towers, it served as a prototype for an unbuilt series of speculative houses to be constructed in Melrose Park, Illinois. The house has been moved and reconfigured as a part of the public Elmhurst Art Museum. He also built a residence for John M. van Beuren on a family estate near Morristown, New Jersey.

Mies designed two buildings for the Museum of Fine Arts, Houston (MFAH) as additions to the Caroline Wiess Law Building. In 1953, the MFAH commissioned Mies van der Rohe to create a master plan for the institution. He designed two additions to the building—Cullinan Hall, completed in 1958, and the Brown Pavilion, completed in 1974. A renowned example of the International Style, these portions of the Caroline Wiess Law Building comprise one of only two Mies-designed museums in the world.[25]

Mies's last work was the Neue Nationalgalerie art museum, the New National Gallery for the Berlin National Gallery. Considered one of the most perfect statements of his architectural approach, the upper pavilion is a precise composition of monumental steel columns and a cantilevered (overhanging) roof plane with a glass enclosure. The simple square glass pavilion is a powerful expression of his ideas about flexible interior space, defined by transparent walls and supported by an external structural frame. Art installations by Ulrich Rückriem (1998) or Jenny Holzer, as much as exhibitions on the work of Renzo Piano or Rem Koolhaas have demonstrated the exceptional possibilities of this space.

The glass pavilion is a relatively small portion of the overall building, serving as a symbolic architectural entry point and monumental gallery for temporary exhibits. A large podium building below the pavilion accommodates most of the museum's total built area with conventional white-walled art gallery spaces and support functions. A large window running along all the West facade opens these spaces up to the large sculpture garden which is part of the podium building.

Mies served as the last director of Berlin's Bauhaus, and then headed the department of architecture, Illinois Institute of Technology in Chicago, where he developed the Second Chicago School. He played a significant role as an educator, believing his architectural language could be learned, then applied to design any type of modern building. He set up a new education at the department of architecture of the Illinois Institute of Technology in Chicago replacing the traditional Ecole des Beaux-Art curriculum by a three-step-education beginning with crafts of drawing and construction leading to planning skills and finishing with theory of architecture (compare Vitruvius: firmitas, utilitas, venustas). He worked personally and intensively on prototype solutions, and then allowed his students, both in school and his office, to develop derivative solutions for specific projects under his guidance.

Some of Mies' curriculum is still put in practice in the first and second year programs at IIT, including the precise drafting of brick construction details so unpopular with aspiring student architects. When none was able to match the quality of his own work, he agonized about where his educational method had gone wrong. Nevertheless, his achievements in creating a teachable architecture language that can be used to express the modern technological era survives until today.

Mies placed great importance on education of architects who could carry on his design principles. He devoted a great deal of time and effort leading the architecture program at IIT. Mies served on the initial Advisory Board of the Graham Foundation in Chicago. His own practice was based on intensive personal involvement in design efforts to create prototype solutions for building types (860 Lake Shore Drive, the Farnsworth House, Seagram Building, S. R. Crown Hall, The New National Gallery), then allowing his studio designers to develop derivative buildings under his supervision.

Mies's grandson Dirk Lohan and two partners led the firm after he died in 1969. Lohan, who had collaborated with Mies on the New National Gallery, continued with existing projects but soon led the firm on his own independent path. Other disciples continued Mies's architectural language for years, notably Gene Summers, David Haid, Myron Goldsmith, Y.C. Wong, Jacques Brownson, and other architects at the firms of C.F. Murphy and Skidmore, Owings & Merrill.

But while Mies' work had enormous influence and critical recognition, his approach failed to sustain a creative force as a style after his death and was eclipsed by the new wave of Post Modernism by the 1980s. Proponents of the Post Modern style attacked the Modernism with clever statements such as "less is a bore" and with captivating images such as Crown Hall sinking in Lake Michigan. Mies had hoped his architecture would serve as a universal model that could be easily imitated, but the aesthetic power of his best buildings proved impossible to match, instead resulting mostly in drab and uninspired structures rejected by the general public. The failure of his followers to meet his high standard may have contributed to demise of Modernism and the rise of new competing design theories following his death.

Over the last twenty years of his life, Mies developed and built his vision of a monumental "skin and bones" architecture that reflected his goal to provide the individual a place to fulfill himself in the modern era. Mies sought to create free and open spaces, enclosed within a structural order with minimal presence.

The Ludwig Mies van der Rohe Archive, an administratively independent section of the Museum of Modern Art's department of architecture and design, was established in 1968 by the museum's trustees. It was founded in response to the architect's desire to bequeath his entire work to the museum. The archive consists of about nineteen thousand drawings and prints, one thousand of which are by the designer and architect Lilly Reich (1885–1947), Mies van der Rohe's close collaborator from 1927 to 1937; of written documents (primarily, the business correspondence) covering nearly the entire career of the architect; of photographs of buildings, models, and furniture; and of audiotapes, books, and periodicals.

Archival materials are also held by the Ryerson & Burnham Libraries at the Art Institute of Chicago. The Ludwig Mies van der Rohe Collection, 1929–1969 (bulk 1948–1960) includes correspondence, articles, and materials related to his association with the Illinois Institute of Technology. The Ludwig Mies van der Rohe Metropolitan Structures Collection, 1961–1969, includes scrapbooks and photographs documenting Chicago projects.

Other archives are held at the University of Illinois at Chicago (personal book collection), the Canadian Center for Architecture (drawings and photos) in Montreal, the Newberry Library in Chicago (personal correspondence), and at the Library of Congress in Washington D.C. (professional correspondence).

^Compare Arthur Lubow's "The Contextualizer,"New York Times. April 6, 2008, p. 4; excerpt, "...a skyscraper that Nouvel (adapting a term from the artist Brâncuși) called the "tour sans fins," or endless tower. Conceived as a kind of minaret alongside the squat, monumental Grande Arche de La Défense, the endless tower has taken on some of the mystique of Mies van der Rohe's unbuilt Friedrichstrasse glass skyscraper of 1921. To obscure its lower end, the tower was designed to sit within a crater. Its facade, appearing to vanish in the sky, changed as it rose, from charcoal-colored granite to paler stone, then to aluminum and finally to glass that became increasingly reflective, all to enhance the illusion of dematerialization."

Aachen
–
Aachen or Bad Aachen, traditionally known in English and French as Aix-la-Chapelle, is a spa and border city in North Rhine-Westphalia, Germany. Aachen was the residence of Charlemagne, and, from 936 to 1531. Aachen is the westernmost city in Germany, located near the borders with Belgium, RWTH Aachen University is located in the city. Aachens industries include science, engineering and information technology, in 2009, Aachen was ranked eighth among cities in Germany for innovation. The location has been inhabited by humans since the Neolithic era, about 5,000 years ago, latin Aquae figures in Aachens Roman name Aquae granni, which meant waters of Grannus, referring to the Celtic god of healing who was worshipped at the springs. Aachens name in French and German evolved in parallel, Aachens local dialect is called Öcher Platt and belongs to the Ripuarian language. Bronze Age settlement is evidenced by the remains of barrows found, for example, during the Iron Age, the area was settled by Celtic peoples who were perhaps drawn by the marshy Aachen basins hot sulphur springs where they worshipped Grannus, god of light and healing. Later, the 25-hectare Roman spa resort town of Aquae Granni was, according to legend, founded by Grenus, under Hadrian, a kind of forum, surrounded by colonnades, connected the two spa complexes. There was also a residential area, part of it inhabited by a flourishing Jewish community. The Romans built bathhouses near Burtscheid, a temple precinct called Vernenum was built near the modern Kornelimünster/Walheim. Today, remains have been found of three bathhouses, including two fountains in the Elisenbrunnen and the Burtscheid bathhouse, Roman civil administration in Aachen broke down between the end of the 4th and beginning of the 5th centuries. Rome withdrew its troops from the area, but the town remained populated, by 470, the town came to be ruled by the Ripuarian Franks and subordinated to their capital, Cologne. Einhard mentions that in 765–6 Pepin spent both Christmas and Easter at Aquis villa, which must have been equipped to support the royal household for several months. In the year of his coronation as king of the Franks,768, Charlemagne spent most winters in Aachen between 792 and his death in 814. Aachen became the focus of his court and the centre of his empire. In 936, Otto I was crowned king of East Francia in the church built by Charlemagne. During the reign of Otto II, the nobles revolted and the West Franks, under Lothair, Aachen was attacked again by Odo of Champagne, who attacked the imperial palace while Conrad II was absent. Odo relinquished it quickly and was killed soon afterwards, the palace and town of Aachen had fortifying walls built by order of Emperor Frederick Barbarossa between 1172 and 1176

Kingdom of Prussia
–
It was the driving force behind the unification of Germany in 1871 and was the leading state of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg, the kings of Prussia were from the House of Hohenzollern. Prussia was a power from the time it became a kingdom, through its predecessor, Brandenburg-Prussia. Prussia continued its rise to power under the guidance of Frederick II, more known as Frederick the Great. After the might of Prussia was revealed it was considered as a power among the German states. Throughout the next hundred years Prussia went on to win many battles and it was because of its power that Prussia continuously tried to unify all the German states under its rule. Attempts at creation of a federation remained unsuccessful and the German Confederation collapsed in 1866 when war ensued between its two most powerful states, Prussia and Austria. The North German Confederation which lasted from 1867–1871, created a union between the Prussian-aligned states while Austria and most of Southern Germany remained independent. The North German Confederation was seen as more of an alliance of military strength in the aftermath of the Austro-Prussian War, the German Empire lasted from 1871–1918 with the successful unification of all the German states under Prussian hegemony. This was due to the defeat of Napoleon III in the Franco-Prussian War of 1870–71, in 1871, Germany unified into a single country, minus Austria and Switzerland, with Prussia the dominant power. Prussia is considered the predecessor of the unified German Reich. The Kingdom left a significant cultural legacy, today notably promoted by the Prussian Cultural Heritage Foundation, in 1415 a Hohenzollern Burgrave came from the south to the March of Brandenburg and took control of the area as elector. In 1417 the Hohenzollern was made an elector of the Holy Roman Empire, after the Polish wars, the newly established Baltic towns of the German states including Prussia, suffered many economic setbacks. Many of the Prussian towns could not even afford to attend political meetings outside of Prussia, the towns were poverty stricken, with even the largest town, Danzig, having to borrow money from elsewhere to pay for trade. Poverty in these towns was partly caused by Prussias neighbors, who had established and developed such a monopoly on trading that these new towns simply could not compete and these issues led to feuds, wars, trade competition and invasions. However, the fall of these gave rise to the nobility, separated the east and the west. It was clear in 1440 how different Brandenburg was from the other German territories, not only did it face partition from within but also the threat of its neighbors. It prevented the issue of partition by enacting the Dispositio Achillea which instilled the principle of primogeniture to both the Brandenburg and Franconian territories, the second issue was solved through expansion

German Empire
–
The German Empire was the historical German nation state that existed from the unification of Germany in 1871 to the abdication of Kaiser Wilhelm II in 1918, when Germany became a federal republic. The German Empire consisted of 26 constituent territories, with most being ruled by royal families and this included four kingdoms, six grand duchies, five duchies, seven principalities, three free Hanseatic cities, and one imperial territory. Although Prussia became one of kingdoms in the new realm, it contained most of its population and territory. Its influence also helped define modern German culture, after 1850, the states of Germany had rapidly become industrialized, with particular strengths in coal, iron, chemicals, and railways. In 1871, it had a population of 41 million people, and by 1913, a heavily rural collection of states in 1815, now united Germany became predominantly urban. During its 47 years of existence, the German Empire operated as an industrial, technological, Germany became a great power, boasting a rapidly growing rail network, the worlds strongest army, and a fast-growing industrial base. In less than a decade, its navy became second only to Britains Royal Navy, after the removal of Chancellor Otto von Bismarck by Wilhelm II, the Empire embarked on a bellicose new course that ultimately led to World War I. When the great crisis of 1914 arrived, the German Empire had two allies, Italy and the Austro-Hungarian Empire, Italy, however, left the once the First World War started in August 1914. In the First World War, German plans to capture Paris quickly in autumn 1914 failed, the Allied naval blockade caused severe shortages of food. Germany was repeatedly forced to send troops to bolster Austria and Turkey on other fronts, however, Germany had great success on the Eastern Front, it occupied large Eastern territories following the Treaty of Brest-Litovsk. German declaration of unrestricted submarine warfare in early 1917 was designed to strangle the British, it failed, but the declaration—along with the Zimmermann Telegram—did bring the United States into the war. Meanwhile, German civilians and soldiers had become war-weary and radicalised by the Russian Revolution and this failed, and by October the armies were in retreat, Austria-Hungary and the Ottoman Empire had collapsed, Bulgaria had surrendered and the German people had lost faith in their political system. The Empire collapsed in the November 1918 Revolution as the Emperor and all the ruling monarchs abdicated, and a republic took over. The German Confederation had been created by an act of the Congress of Vienna on 8 June 1815 as a result of the Napoleonic Wars, German nationalism rapidly shifted from its liberal and democratic character in 1848, called Pan-Germanism, to Prussian prime minister Otto von Bismarcks pragmatic Realpolitik. He envisioned a conservative, Prussian-dominated Germany, the war resulted in the Confederation being partially replaced by a North German Confederation in 1867, comprising the 22 states north of the Main. The new constitution and the title Emperor came into effect on 1 January 1871, during the Siege of Paris on 18 January 1871, William accepted to be proclaimed Emperor in the Hall of Mirrors at the Palace of Versailles. The second German Constitution was adopted by the Reichstag on 14 April 1871 and proclaimed by the Emperor on 16 April, the political system remained the same. The empire had a parliament called the Reichstag, which was elected by universal male suffrage, however, the original constituencies drawn in 1871 were never redrawn to reflect the growth of urban areas

Chicago
–
Chicago, officially the City of Chicago, is the third-most populous city in the United States. With over 2.7 million residents, it is the most populous city in the state of Illinois, and it is the county seat of Cook County. In 2012, Chicago was listed as a global city by the Globalization and World Cities Research Network. Chicago has the third-largest gross metropolitan product in the United States—about $640 billion according to 2015 estimates, the city has one of the worlds largest and most diversified economies with no single industry employing more than 14% of the workforce. In 2016, Chicago hosted over 54 million domestic and international visitors, landmarks in the city include Millennium Park, Navy Pier, the Magnificent Mile, Art Institute of Chicago, Museum Campus, the Willis Tower, Museum of Science and Industry, and Lincoln Park Zoo. Chicagos culture includes the arts, novels, film, theater, especially improvisational comedy. Chicago also has sports teams in each of the major professional leagues. The city has many nicknames, the best-known being the Windy City, the name Chicago is derived from a French rendering of the Native American word shikaakwa, known to botanists as Allium tricoccum, from the Miami-Illinois language. The first known reference to the site of the current city of Chicago as Checagou was by Robert de LaSalle around 1679 in a memoir, henri Joutel, in his journal of 1688, noted that the wild garlic, called chicagoua, grew abundantly in the area. In the mid-18th century, the area was inhabited by a Native American tribe known as the Potawatomi, the first known non-indigenous permanent settler in Chicago was Jean Baptiste Point du Sable. Du Sable was of African and French descent and arrived in the 1780s and he is commonly known as the Founder of Chicago. In 1803, the United States Army built Fort Dearborn, which was destroyed in 1812 in the Battle of Fort Dearborn, the Ottawa, Ojibwe, and Potawatomi tribes had ceded additional land to the United States in the 1816 Treaty of St. Louis. The Potawatomi were forcibly removed from their land after the Treaty of Chicago in 1833, on August 12,1833, the Town of Chicago was organized with a population of about 200. Within seven years it grew to more than 4,000 people, on June 15,1835, the first public land sales began with Edmund Dick Taylor as U. S. The City of Chicago was incorporated on Saturday, March 4,1837, as the site of the Chicago Portage, the city became an important transportation hub between the eastern and western United States. Chicagos first railway, Galena and Chicago Union Railroad, and the Illinois, the canal allowed steamboats and sailing ships on the Great Lakes to connect to the Mississippi River. A flourishing economy brought residents from rural communities and immigrants from abroad, manufacturing and retail and finance sectors became dominant, influencing the American economy. The Chicago Board of Trade listed the first ever standardized exchange traded forward contracts and these issues also helped propel another Illinoisan, Abraham Lincoln, to the national stage

Illinois
–
Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 6th most populous state and 25th largest state in terms of land area, the word Illinois comes from a French rendering of a native Algonquin word. For decades, OHare International Airport has been ranked as one of the worlds busiest airports, Illinois has long had a reputation as a bellwether both in social and cultural terms and politics. With the War of 1812 Illinois growth slowed as both Native Americans and Canadian forces often raided the American Frontier, mineral finds and timber stands also had spurred immigration—by the 1810s, the Eastern U. S. Railroads arose and matured in the 1840s, and soon carried immigrants to new homes in Illinois, as well as being a resource to ship their commodity crops out to markets. Railroads freed most of the land of Illinois and other states from the tyranny of water transport. By 1900, the growth of jobs in the northern cities and coal mining in the central and southern areas attracted a new group of immigrants. Illinois was an important manufacturing center during both world wars, the Great Migration from the South established a large community of African Americans in Chicago, who created the citys famous jazz and blues cultures. Three U. S. presidents have been elected while living in Illinois, Abraham Lincoln, Ulysses S. Grant, additionally, Ronald Reagan, whose political career was based in California, was the only U. S. president born and raised in Illinois. Today, Illinois honors Lincoln with its official slogan, Land of Lincoln. The Abraham Lincoln Presidential Library and Museum is located in the capital of Springfield. Illinois is the spelling for the early French Catholic missionaries and explorers name for the Illinois Native Americans. American scholars previously thought the name Illinois meant man or men in the Miami-Illinois language and this etymology is not supported by the Illinois language, as the word for man is ireniwa and plural men is ireniwaki. The name Illiniwek has also said to mean tribe of superior men. The name Illinois derives from the Miami-Illinois verb irenwe·wa he speaks the regular way and this was taken into the Ojibwe language, perhaps in the Ottawa dialect, and modified into ilinwe·. The French borrowed these forms, changing the ending to spell it as -ois. The current spelling form, Illinois, began to appear in the early 1670s, the Illinois name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans, the Koster Site has been excavated and demonstrates 7,000 years of continuous habitation

It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties.

Neue Nationalgalerie
–
The Neue Nationalgalerie at the Kulturforum is a museum for modern art in Berlin, with its main focus on the early 20th century. It is part of the National Gallery of the Berlin State Museums, the museum building and its sculpture gardens were designed by Ludwig Mies van der Rohe and opened in 1968. The collection features a number of highlights of modern 20th-century art. Particularly well represented are Cubism, Expressionism, the Bauhaus and Surrealism, the collection owns masterpieces of artists like Pablo Picasso, Ernst Ludwig Kirchner, Joan Miró, Wassily Kandinsky and Barnett Newman. The design of the building, despite its large site, allows for the display of only a part of the collection. The plan of the Neue Nationalgalerie is divided into two distinct stories, the upper story serves as an entrance hall as well as the primary special exhibit gallery, totaling 2,683 m2 of space. It is elevated from street level and only accessible by three flights of steps, though it only comprises a small portion of the total gallery space, the exhibition pavilion stands boldly as the building’s primary architectural expression. Eight cruciform columns, two on each length placed so as to avoid corners, support a square pre-stressed steel roof plate 1.8 meters thick, an eighteen-meter cantilever allows for ample space between the gallery’s glazed façade and eight supporting columns. Mies’ office studied this cantilever extensively in various scaled models in order to ensure its stability as well as the seeming flatness of the roof plate. The floor-to-ceiling height reaches 8.4 meters, and the space is laid out on a 3. 6-meter square dimensional grid, black anodized aluminum “egg crates” fit within the grid house lighting fixtures, with air ducts suspended above. The lower story serves primarily as housing for the permanent collection, though it also includes a library, offices, and a shop and café. A rooftop plaza further extends the museum’s exhibition space, in 1956, José M. Bosch, President of Ron Bacardí y Compañía approached Mies to commission the design of a new office space. He was particularly interested in an open plan, and the relatively simple idea Mies came up with involved a square roof plate supported on each side by two columns. The Bacardí Building was abandoned in September 1960 due to political unrest in Cuba. Georg Schaefer, a wealthy industrialist living in Schweinfurt approached Mies about the construction of a museum for his art collection during the summer of 1960. A modest initial plan was drawn for the structure, but later that year Mies decided to reconfigure the unbuilt Bacardí project to fit Schaefer’s program as he wished to see it built. Consequently, a model of the Bacardí project this time rendered in steel rather than concrete was created. The two museum projects, though different in scale, where to be essentially identical in form

Farnsworth House
–
The Farnsworth House was designed and constructed by Ludwig Mies van der Rohe between 1945 and 1951. It is a weekend retreat in a once-rural setting, located 55 miles southwest of Chicagos downtown on a 60-acre estate site, adjoining the Fox River, south of the city of Plano. Mies created a 1, 500-square-foot house that is recognized as an iconic masterpiece of International Style of architecture. The home was designated a National Historic Landmark in 2006, after joining the National Register of Historic Places in 2004, the house is currently owned and operated as an historic house museum by the historic preservation group, National Trust for Historic Preservation. In September 2008, the house was flooded by rains from the remnants of Hurricane Ike, water levels reached about 18 inches above the floor and the 5 foot stilts upon which the house rests. Much of the furniture was saved by elevating it above the flood waters, the house was closed to the public for the remainder of 2008 for repairs and reopened for public visitation in spring 2009. Ludwig Mies van der Rohe was retained by Dr. Edith Farnsworth to design a weekend retreat during a party in 1945. The wealthy client was highly intelligent, articulate, and intent on building a special work of modern architecture. The program was to design the house as if it were for himself, Farnsworth had purchased the riverfront property from the publisher of the Chicago Tribune, Colonel Robert R. McCormick. Mies developed the design in time for it to be included in an exhibit on his work at MOMA, after completion of design, the project was placed on hold awaiting an inheritance from an ailing aunt. Mies was to act as the contractor as well as architect. Work began in 1950 and was completed in 1951. The commission was a one for any architect, but was marred by a very publicized dispute between Farnsworth and Mies that began near the end of construction. The total cost of the house was $74,000 in 1951, near the completion of construction, Mies filed a lawsuit for non-payment of $28,173 in construction costs. The owner then filed a suit for damages due to alleged malpractice. Mies attorneys proved that Farnsworth had approved the plans and budget increases, Farnsworths malpractice accusations were dismissed as unsubstantiated. It was a bitter and hollow victory for Mies, considering the publicity that followed. The conflict resulted in a site and an unfurnished interior
